One of the most debated aspects of daily and correspondence chess is the role of analysis. With more time per move, players naturally want to explore positions deeply—but where is the line between fair study and unfair assistance? This guide explains the rules, ethics, and best practices so you can improve responsibly while respecting the spirit of the game.
Generally allowed: personal thinking, handwritten notes, opening databases, and reference books. These simulate the preparation stage of OTB chess.
Engines and external move-suggestion software are almost always banned. Using them during a game is considered cheating.
Some platforms differ on what resources are acceptable. Always read the rules carefully to avoid unintentional violations.
The purpose of daily chess is to train your own calculation and planning. Outsourcing thinking to engines defeats that purpose.
Using forbidden tools erodes trust in correspondence play. Respect for your opponent is central to healthy competition.
True improvement comes from your own thinking process, not from engine lines. Your mistakes today are tomorrow’s lessons.
Pick a position from your game and write down three candidate moves. Calculate each for at least two moves deep before choosing.
Check your opening in a reference book or database. Write a note on how it aligns with your plan, but stop before relying too heavily on memorization.
Once the game ends, run it through an engine. Compare your thinking with the computer’s evaluation to spot blind spots.
Spending hours on a single move can create tunnel vision. Balance calculation depth with practicality.
Copying book moves blindly without understanding reduces learning value. Use databases as guides, not crutches.
Using engines when prohibited risks account penalties and ruins the spirit of play. Always respect platform guidelines.
Typically your own thinking, notes, databases, and books. Engines are banned in most cases.
No. Engine use during active games is against fair play rules on most platforms.
Yes, they are often allowed and simulate preparation. Always confirm site-specific rules.
